Maybe, but I don't think it's important. If grep happens to run under UTF-8 and only a libpcre without utf8 support is available, the call to exec_compile fails with a nice "this version of PCRE is not compiled with PCRE_UTF8 support" message. If user encounters this error, he can export LANG=C, or rebuild libpcre with --enable-utf8 without recompiling grep. > and if > so to define something like HAVE_LIBPCRE_UTF8 > then (or to have configure abort with an error > message about this being absolutely needed)? If I really put in a test program and run it with something like AC_RUN_IFELSE, I would only issue a warning, since grep itself is perfectly functional. Putting in a HAVE_LIBPCRE_UTF8 would capture the situation at configure time, and nullify attempts by the user to rebuild pcre and get grep -P to automagically work.
